NrTnn STATES PATENT FFICE@ CAN-FILLING MACHINE.

SPECIFICATION forming part of Letters Patent No. 391,795, dated October30, 1888.

A pplcation iiled March 17,1885.

To @ZZ whom it may @encerrar Be it known that I, JOHNT B. HO'DAPI?, acitizen of the United States, residing at Mankato, in the county of BlueEarth and State of Minnesota, have invented certain new and usefulImprovements in Can-Filling Machines; and

I do hereby declare the following to be a full, clear, and exactdescription of the invention, such as will enable others skilled in theart to which it appertains to make and use the same.

This invention relates to can-filling ma chines; and it consists in thenovel construction and combination of the parts, as herein after fullydescribed and claimed.

In the drawings, Figure l is a side view of the complete machine. Fig. 2is a plan View of the gage-plate and the end of the dippingtrough. Fig.3 is a front view showing the hopper and cantable in section. Fig. 4 isa plan View of a portion of the feed pan and the feed mechanism underit. Fig. 5 is a vertical cross-section on line x x in Fig. Fig. 6 is across-section through the receptacles for the cans, and Fig. 7 is aperspective View of the plunger.

A is the frame of the machine, and A is the dipping-trough. Fast andloose driving-belt pulleys a e are secured upon the shaft I3,which isjournaled in the frame A, and abeltshifter, b, is provided for stoppingand starting the machine.

B is the ily-wheel, and b is a pinion, both of which are secured toshaft B.

O is a shaft, also journaled in the frame and provided with the toothedwheel C', gearing into pinion b, and provided also with the pinion c.

D is a shalt journaled in the upper part of the frame and provided withthe toothed wheel c', gearing into pinion c. The crank D and beveledpinion d are also secured upon shaft D.

E is a vertical shaft provided at the top with the beveled wheel. d',gearing into pinion d.

Fi is the feed-pan, secured to the frame, and c are revolving armssecured upon shaft E within the pan. A small beveled wheel, e', issecured upon the shaft E for driving the feedcylinder F, which issecured upon the shaft F', which has also the beveled wheel f securedupon it and gearing into the said wheel e.

(No model.)

Gf is the feed-hopper, and G is the Iced'cylinder casing at the lowerpart of the hopper.

The feedcylinder F has iixed ilanged arms f and straight arms g. Looseiianged arms g are provided and adjustably secured to the said straightarms by screws. The lianges of arms g slide under the ilangcs ofthefixed arms, and the amount of material fed from the hopper maybe variedby means of the screws, which cause the loose hanged arms to approach orrecede from the xed arms, and thereby vary the size of the interveningpockets for material in the feed-cylinder.

His the throatpiece, into which the material from the feedeylinder isswept by the revolving arms e, and H are the iillers, secured to theunder side of the throatpieee and separated from each other by thepartition h, which projects upwardly from the bottom. of the fillers andis not connected to their sides.

I is a plunger provided with the square pl unger-rod I, sliding in theguides fi, and operated through the connecting-rod t" by the crank D.The plunger has a central hole, into which the partition 7L may enterwhen the plunger descends, and li are plates which strengthen theplunger and slide in the narrow spaces between the ends of the partitionand the sides of the fillers.

VJ is the feed-slide, and J is the cover-plate at the bottom of thefillers,which supports the slide in close contact with the base of theillers. The base of the fillers, the slide, and its cover-plate are eachprovided with similar holes, j and j', which register when material isbeing forced out of the fillers into the cans by the plunger. Of theseholes, j is asegrnent of a circle and is for the passage of material,and j is a small round air-hole.

K is a cross-hole which is formed laterally through the side of eachfiller into the air-hole j', and K is a valve which closes the top endof hole j inside each filler. rlhe valves K prevent the material passingdownward through holes j when the plunger descends and permit the escapeof air from the cans through the holes K. When the plunger ascends, thevalves K admit air from the crossholes K to the under side of theplunger, so that the contents of the can are not sucked up again.

IOO

L is a cam provided with rollers Z, which bear against the plate Z,secured to the end of the feed-slide. These rollers roll upon the plateZ and hold the feed-slide so that it closes the holes j j of the feedersduring the greater part of the revolution of the cani L, which issecured upon the vertical shaft E.

L is a spring, which pulls open the feed-slide directly the cam leavesthe plate Z. The synchronous motion of the feedcylinder and therevolving arms alternates with the descent of the plunger, and thefeed-slide Ais opened in time to allow the plunger to force the materialout of the fillers into the cans. The continued revolution of the cam Lcloses the feed-slide when the downstroke of the plunger is complcted.

M is the can-table,secured to the framing A, and M is avertically-rising plate normally supported in a recess in the top of thetable and flush with its surface. This plate is provided with the stemm, and m is a spring surrounding the stem and bearing against the leverN, which is pivoted to the frame A at one end. A roller, a, isjournaledat the other end of the lever, and N is a face-cam secured on thevertical shaft E. The roller n is raised by the cam just before thefeedslide is opened, so that the cans which are standing on the saidplate are pressed tightly against the under side of the coverplate J. Aguide, n, is secured tothe top of table M, for keeping cach pair of cansat the proper distance apart until they pass onto the plate M.

O is an endless carrier, consisting of two side chains united bycross-bars O, for moving the cans along. This carrier is supported bythe carrier-wheels o, journaled upon shafts at the front end of thecan-table and at the necessary points in the di pping-trough to make thecans pass through it. The carrier is moved by the carrier-wheels o',secured upon the shaft P, journaled at the rear end of the can-table.This shaft Pis provided with the ratchetwheel P for turning it, and p isa slotted arm pivoted on the shaft I?, and provided with thespring-pawlp for operating the ratchet.

Q is an adjustable connecting-rod, which operates the arm p from thecrank D.

Q] are the receptacles for the cans,supported above the rear end of thecantable by the braclgets q, and qare adjustable guides bolted to thelowerv ends of the said receptacles for straightening the tops of thecans as they pass from under the receptacles.

The motion of the carrier is adj usted so that two empty cans aredelivered upon the vertically-rising plate M, and are held between itand the plate J just before each descent of the plunger in the fillersand the opening of the feed-slide.

The carrier O passes through the dippingtrough A and returns underneathit vto the rear end of the machine. It and R are guideplates secured,respectively, at the receiving and delivery ends of the trough forsupporting the cans as they descend and ascend. A. coil ofsteam-pipes,1', is provided in the-bottom of the trough for the cans to pass over,and r is a plate supported within the trough for keeping the tops ofthecans straight. The trough is partly filled with water or other liquid inwhich it :may be desired to dip the cans, and this liquid is keptboiling by the steam-pipes r, so that the contents of the cans areheated and steam is formed in them,which drives out all the air. Whenthe cans come up out of the trough, they are ready to be capped, bywhich operation they are made air-tight, and their contents therebypreserved from decay.

S is the gage-plate, supported by brackets S at the delivery end ot' thetrough. This plate is provided with the strips s, for spacing the cans,as they pass onto it from the guideplate R, which is also provided withthe tapering guide-stripr at its upper end.

T are curved adjustable guides for evening the tops of the cans as theypass over the gage-plate. These guides are provided with slotted arms Tand are secured tothe brackets S by the bolts t.

The shafts which carry the carrier-wheels o are journaled inloop-brackets U, which are secured to the sides of the trough by thesetscrews U, so that the position of the said wheels can easily bevaried. In asimilar manner the 'brackets V, which carry the guideplater', are held to the trough by set-screws V', so that the height of theplate may be rcgulated.

Vha't I claim is- J.
